Yet more new minor moons of Jupiter discovered

[JackHiggins]

ANOTHER 6 minor moons of Jupiter have been discovered, bringing the total to a whopping 58.

If anyone's interested, heres the ssc

And, this time the elements are actually accurate (body centred), thanks to Grant's advice from the last time!

Have fun...

[billybob884]

oh boy! theres probably still hundreds more to find

[JackHiggins]

One of the discoverers of the newest batch of moons said in an interview he thinks there could be up to a hundred moons larger that 1km radius, and thousands more pebbles out there!!

If celestia had a seperate class "minormoons" that you could turn on & off the orbits for seperately it would be handy...!!

I've fixed my tinymoons.zip file, it now has proper body-centred elements for ALL moons known in the solar system, and you can get it at my website http://homepage.eircom.net/~jackhiggins/celestia/
Some moons may overlap with ones in the most recent version of minormoons.ssc

Jack:
Sorry, I maybe didn't explain things very well last time.
There are two different problems, one with the ascending node and one with the inclination. Getting body-centred data from Horizons only fixes the inclination. You've still got to adjust the Horizons ascending node from Earth-equatorial to the ecliptic coordinates used by Celestia, by doing the little sum I mentioned last time.
For Jupiter, you need to subtract 40.863031 from the ascending nodes provided by Horizons.

Right now we're not sure about the boundaries between gas giants and stars and planets and asteroids. Imagine the confusion if we find out there's no line between ring fragments and the tiniest moons...

[JackHiggins]

Grant-

Oops... I knew i should have asked you were these elements right before putting them up... Thanks for the correction i'll be more careful next time!!! (Or maybe i'll just check with you first...)

[JackHiggins]

All right, NOW they're correct
